I've always had dogs -- well, except when the Army was transferring us around every time we turned around.
I find dogs very endearing and comforting (I guess they touch some maternal instinct or something). I like BIG dogs, like labradors, pit bulls, german shepherds, etc. I have found them to be, at least in my experience, gentler than many of the smaller breeds, and generally, the bigger they are, the bigger a mush they are. I always get adult dogs from a rescue.
My present dog, Bonnie the pit bull/Staffie mix, was abused and neglected in her former life, and now she is the biggest mush in the world. I adopted her a couple years ago at 7+ years old, got her medical issues taken care of, got her on decent food, and she has settled in to be the best dog in the whole world. She went from being quite fearful to now loving everyone in the whole world (except the mailman, for some reason) and recently almost kissed my plumber to death. She even loves the people at my vet's office. She just beams with the joy of being alive.
